Optimal triangulations for piecewise linear approximations of non-convex variable products
Robert Burlacu, Lukas Hager, Robert Hildebrand
We show optimal triangulations for piecewise linear (PWL) approximations of indefinite quadratic functions over the plane. Optimal triangulations have minimum triangle density whil…

Parabolic Approximation & Relaxation for MINLP
Adrian GöÃ, Robert Burlacu, Alexander Martin
We propose an approach based on quadratic approximations for solving general Mixed-Integer Nonlinear Programming (MINLP) problems. Specifically, our approach entails the global app…
